SPECIFICATION forming part of Letters Patent No. 718,587, dated January13, 1903.

Application filed December 11, 1901. Serial No. 85,486. (No model.)

To all whmn it may concern:

Beit known that I, EDWARD S. STIMPSON, a citizen of the United States,and a resident of Hopedale, county of Worcester, State of Massachusetts,have invented an Improvementin Automatic Filling-Replenishing Looms, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts.

This invention relates to looms provided with automaticfilling-replenishing mechanism of the type wherein .the running shuttleis provided as occasion demands with a fresh supply of filling, andheretofore the shuttle has been provided with anautomatically-selfthreading device.

In my present invention I have devised means independent of the shuttlefor positively threading the same when a fresh fillingsupply is insertedin the shuttle, and the-latter instead of being provided with athreading device is made with a thread-delivery eye having a continuousrim. In other words, such delivery-eye is merely a hole made in the sidewall of the shuttle, and the filling is threaded through this eye bynovel threading means, which form the main part of my invention.

Figure 1 is a right-hand side elevation of a portion of a loom providedwith automatic fillingreplenishing mechanism, the feeder thereof and thelay being shown in section and with one embodiment of my invention beingapplied thereto. Fig. 2 is a detail of a portion of the apparatus shownin Fig. 1, but with the shuttle-threading means in position to threadthe shuttle, afresh supply of filling having been just transferred tothe latter. Fig. 3 is a front elevation of the apparatus shown in Fig. 1with the parts in the same relative position. Fig. a is a plan View,partly broken out, of the end of the shuttle provided with the threaddelivery eye. Fig. 5 is a front elevation thereof. Fig. 6 is aperspective detail of a part of the threading means detached. Fig. 7 isan enlarged side elevation of the thread-catcher as it appears when itenters the shuttle preparatory to threading sition.

it, and Fig. 8 is a similar view showing how the thread is caught andheld as the catcher is withdrawn from the shuttle.

Referringto Figs. 1 and 3, the loom-frame A, the lay A slotted at 10below one of the shuttle-boxes, the hunter C on the lay, and thefillingfeeder F are of well-known construction, the two disks a a whichsupport between them the filling-carriers I), being connected torotatein unison on a stud a, rigidly secured to a stand A mounted on thebreastbeam A, the filling ends being led over an outer disk I) (seedotted lines, Fig. 3) and thence to a holding-stud said stud and thedisk b rotating intermittingly to present the filling-carriers one byone in transferring po- The feeder and the means for effecting itsrotation are substantially as shown in United States Patent No. 664,790,dated December 25, 1900, and need not be further described herein, as insaid patent the stand A supports a horizontal stud f, on which isloosely mounted the hub f of the transferrer f, extended between thedisks of the feeder, engaging the head of the filling-carrier,-while thetip of the latter is engaged by the notched and downturned end 22 of alateral arm 21,,

rigidly secured to the transferrer f, and a yielding tip-supportf ismounted on an arm f secured to the stud f, as in said patent. Thetransfer of a filling-carrier to the shuttle is effected when a changeoccurs in the condition of the filling in the shuttle-such, forinstance, as its exhaustion to a desired extent or its breakage-such acondition effecting in well-known manner the turning of a rock-shaft din the direction of the arrow '65, the rock-shaft having fast upon it anslot y", entered by a lateral lug on, secured to an arm m, rigidlymounted on a stud 'n pivoted in the lower bifurcated end of a dependingarm f secured to or forming a part of the transferrer-hub f A notcheddog an is secured to the arm m and when the rockshaft (1 is turned inthe direction of the arrow 65, Fig. 1, the shuttle-feeler is through armd swung rearwardly into operative position, and the branch acts to swingthe arm 777. and move the dog m into the path of the hunter C themovement of the dog being therebyeffected in a positive manner. When thehunter engages the dog, the trausferrer is depressed in well-knownmanner to transfer the lowermost filling-carrier in the feeder to theshuttle the lay reaches its forward position, as shown in Fig. 2.

Referring now to Figs. 4 and 5, the shuttle S, having a longitudinalopening 8X for the filling-carrier, which is held therein by suitableholding means, (not shown,) is provided with a rather large aperture 8in its side wall near one end, forming the thread-delivery eye, and atransverse wall 3 separates the opening s from a smaller chamber 3 withwhich the eye 8 communicates. A central longitudinal depression orgroove 5 is made in the shuttle-body in front of the chamber 8 and anotch 6 in alinement therewith is made in the top of the wall 8. \Vhen afilling-carrier is transferred to the shuttle, its filling end, which itwill be remembered is passed around the disk b and fastened to the studD will enter the notch 6 and groove 5, crossing the chamber 5 and, aswill now be described, a thread positioner engages such part of thethread and pushes it down into the chamber into position to be engagedby a thread-catcher which enters the shuttle through the eye 8. Alateral arm h has at its inner end a concave seat 72. Fig. 6, to fit thehub f of the transferrer, to which said arm is secured by screws 8, theouter end of the arm having a socketed enlargement It, provided with adownturned apertu red ear 7?? to loosely embrace the stud f, and thethreadpositioner is secured to the head and is extended rearwardly. Thethread-positioner is shown as a straight blade-like member k, having itsrearend bifurcated and bent to present two downturned fingers 7t 7t,slightly separated and notched or concaved at their tips, as atk", Fig.(5, the normal position of the threadpositioner being shown in Fig. 1,its fingers being so located that when a transfer is effeeted themovement of the transferrer rocks the blade-like arm k and causes thefingers 7a to enter the chamber 5 in the shuttle, the notches engagingthe thread and pressing it down into the chamber. This position of thethread-positioner is shown in Fig. 2, the filling-thread being omittedto avoid confusing the drawing, the deep notch 6 in the wall 3' of theshuttle receiving the thread as it is pushed down into the chamber 8 AnL-shaped leg 13 is loosely mounted on the studfadjacent the head 71, thesocket portion 71. of the latter receiving the hub 17* of said leg, thelatter being held in place by a bentstop-finger f secured to the stud fby a suitable set-screw 10. The foot 19 of the leg 2) is longitudinallyslotted at 12, Figs. 1 and 2, to receive a clamping-bolt 14:, whichpasses through a thin flat extension 19 and adjustably connects it in arigid manner with the leg, the extension being reduced in thicknesstoward its rear end and having its extremity turned up and forward toform a hook 19 which constitutes one member of the thread-catcher. Acooperating member fiis fulcrumed at p on the side of the memberp andhas its rear end slightly upturned, as at 19, (see Figs. 7and 8,) theopposite end of the member 1) being drawn down and tempered toconstitute a spring 137, which at its extremity is bent laterally andinserted in a slot 16 in the extension 19 the spring normally acting tolift the tip of the member 19 so that it lies against the side face ofthe hook 19 as in Fig. 1. The legp is so located on the studf that whenthe said leg is swung into operative position the members 19 19 willenter the eye s of the shuttle when the lay beats up, the front wall bof the shuttle-box B having an opening 79 therein to permit suchmovement.

Referring to Fig. 3, it will be seen that the stud at) is bent down at nand then laterally at m the latter portion being extended far enough topass beneath the lower edge of the extension 19 and as the stud n turnswith the arm m it will be manifest that when the latter is moved tobring the dog m into the path of the hunter C the part 11 of the studwill act upon the extension 19 swinging it and the legp about thestudfinto the position shown in Fig. 2, the bent stop-finger f limitingsuch movement by engaging the leg 1). Of course this positioning of thethread-catcher is effected before the lay heats up, so that as it comesforward, the shuttle being in the box B the extremities of the memberspand p will pass through the openings Z2 and the eye 3 of the shuttleinto the chamber 5 of the shuttle. Ashelf b on the shuttle-box wall b atthe bottom of the opening 5 acts upon the lower edge of the member 19 infront of its fulcrum p tipping said member against the action of itsspring end 19 so that its tip 19 will be depressed into the positionshown in Figs. 2 and 7 and leaving the hookp open. When filling transferis effected, immediately thereafter the positioner k acts with itsfingers 76 upon the thread, pushing thelatter down under the beak of thehook p ,the fingers at such time straddling said hook and the tip of itscooperating member 19 and as the lay begins to move back the thread ispulled completely into the hook, while the transferrer andthread-positioner return to normal position. As the lay recedes thecontrolling-shelf I9 releases the member 19 so that its spring 19immediately rocks it to lift its tip 19 which is beneath thefilling-thread i, Fig. 8, and as the memberp assumes its normal positionwith its tip contiguous to the top of the hook p the thread will benipped between the two adjacent faces, and the bight of thread so heldis pulled through the deliveryeye 3 of the shuttle. One end of the bightleads through the eye into the chamber and thence to the holding-stud band the other end leads through the notch 6 to the filling-carrier inthe shuttle, and when the latter is thrown across the lay the thread isbroken between the stud b and the thread-catcher, the thread at theother side of the latter drawing off through the notch 6 and eye 3 fromthe filling-carrier in the shuttle. After one or more picks the threadbetween the edge of the cloth and the thread-catcher is severed in ithat the shuttle-threading means is entirely independent of the shuttleand that the shuttle is positively threaded by such means. So, too, theshuttle has a thread-delivery eye with a continuous rim, asdistinguished from an eye having a thread-directing slot leadingthereto, the structure of the shuttle being greatly simplified and itsweight decreased. These features are broadly new so far as I am aware,and accordingly my invention is not restricted to the preciseconstruction and arrangement herein shown and described, for the samemay be rearranged or modified in various particulars without departingfrom the spirit and scope of my invention.

When the spring S is free to act, it operates through the rock-shaft dand arm 01 to restore the shuttle-feeler y and the dog in to normalposition, the turning of the arm 'm by or through the action of thecam-slot y permitting the leg 1) and its attached threadcatching meansto return to the position shown in Fig. 1.

The enlarged upper end of the cam-slot per" mits the movement of the dogm and its supporting-arm m when the former is engaged and moved by thehunter 0 as the lay heats up.
